Residual Sugar
Residual Sugar refers to the natural grape sugars that remain in wine after fermentation is complete. It's a key term in winemaking that indicates how sweet or dry a wine is. Wine professionals use this measurement to classify wines and ensure consistency in production. You might see this abbreviated as "RS" in technical documents. Understanding residual sugar is crucial for quality control positions and winemaking roles, as it directly affects the wine's taste, customer satisfaction, and product specifications.
